ABSTRACT
ObjectiveTo investigate the clinical effects of androgen blockade combined treatment for the elderly with middle and late prostate cancer.Methods 63 patients (average age of 69.3 years) with middle and late prostate cancer (above stage T3 ) were studied retrospectively from June 2001 to August 2009.21 cases were treated by operation of bilateral orchidectomy independently.15 cases were treated by castration independently (enantone 3.75 mg or zoladex 3.6 mg/month,hypodermic injection for one year).27 cases were treated by bilateral orchidectomy plus maximum androgen blockade (MAB) (bicalutamide 50 mg,qd,fulutimad 250 mg,rid,po.)Results The survival rates of 1,2,3 years were 100.0％,90.0％,75.0％ in operation group,100.0％,86.7 ％,73.3％ in drug group,and 100.0％,96.2％,84.6％ in MAB group,respectively.The survival rates of 3 years was higher in MAB group than the other groups(x2 =4.460,P＜0.05).The levels of PSA within 3 months decreased and urinary flow rates in three groups increased after treatment than before treatment (t =2.641,3.074,6.703,P ＜ 0.01 ) with no differences among the groups.The relieve period of validity was longer in MAB group than in other groups (F=16.57,P＜0.01 ).Conclusions MAB may be more effective for the elderly with middle and late prostate cancer than castration therapy independently.
ABSTRACT
Objective To evaluate the effect of the urinary reservoir constructed with ileocecum-appendix in the elderly with bladder cancer. Methods From March 2002 to June 2008, 12 cases were treated using ileocecum-appendix as the reservoir after radical cystectomy. They all received the imaging urodynamics examination and were followed up for 1 year. Results The 11 of 12 patients had urinary continence completely. Only 1 case had incontinence and 3 cases had incontinentia urinae at night. Times of uresis were 8-10/day and 3-5/night within 3 months after surgery, and 4-6/day and 0-2/night 6 months after surgery. The urinary output was 150-350 ml/time. Urodynamics showed that mean urinary flow rate was 10.5 ml/s, mean initial bladder pressure was 27 cm H2O, the maximum filling pressure was 35 cm H2O. The average reservoir capacity was 152 ml and 420 ml, respectively. The out let pressure of posterior urethra was 52 cm H2O. The volume of residual urine was 0-65 ml. No evidence of ureteral reflux occurred, no hyperchloremic acidosis was observed. Conclusions Orthotopic bladder reconstruction is considered as an ideal form of urinary diversion characterized by low pressure, larger capacity and continence.
ABSTRACT
Objective To compare the severity of sensorineural hearing impairment resulted from radiotherapy (RT) and radiochemotberapy (CRT) in patients with nasopharyngeal carcinoma (NPC). Methods Between March 2002 and May 2007, 100 initially diagnosed NPC patients in Shandong Tumor Hospital and Qi Lu Hospital were randomized to RT group and CRT group. All patients underwent intensity modulated radiation therapy. In CRT group, concurrent and adjuvant CDDP were administered (CDDP 25 mg/m2/d for 3 days to 4 cycles). Pure tone auditory threshold examination was performed 1 week ,6 months, 1 year and 2 years after the completion of radiotherapy. Statistical analyses were performed using Mann-Whit-ney U test,chi-square test and Fisber's exact probability test. Results The high-frequency threshold was significantly increased in CRT group comparing with RT group at 1- and 2-year after the treatment. In RT group, the hearing threshold was impaired immediately after the treatment, partially recovered within the first year but impaired again after 2 years. In CRT group, hearing threshold was impaired at the same time and kept getting worse until 1 year after radiotherapy, which could not be recovered. Conclusions Patients with NPC treated with radiotherapy and concurrent/adjuvant chemotherapy have more severe sensorineural hearing impairment comparing with those with radiotherapy alone, especially to the high frequency sound in the speech range. Inner ear tissue tolerance should be redefined for patients receiving radiochemotherapy.
